Puppet users - Mar 2013 - Puppet 3.1 - Error: Could not run: undefined method `prune_parameters' for nil:NilClass - fresh install on RHEL 6.4

Trying to get my puppet up and running but running into a slight problem - 
trying to view a resource I get an error for undefined method
 
[root@puppet puppet-dashboard]# puppet resource user root
Error: Could not run: undefined method `prune_parameters'' for
nil:NilClass
[root@puppet puppet-dashboard]# uname -a
Linux puppet.luminexcorp.com 2.6.32-358.0.1.el6.x86_64 #1 SMP Tue Feb 26

[root@puppet puppet-dashboard]# ruby --version
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]
[root@puppet puppet-dashboard]#
[root@puppet puppet-dashboard]# rpm -qa | grep puppet

puppet-dashboard-1.2.22-1.el6.noarch
puppet-server-3.1.0-1.el6.noarch
puppetdb-terminus-1.1.1-1.el6.noarch
 
The --debug output isn''t showing any error that I can see - is there a
way
to capture more debug info to see if I can gather where that 
''prune_parameters'' error is coming from?
